I'm trying to filter jsonPath by type. To extract Integers
I would expect this will return nothing as 'xx' is not integer:
JsonPath.read("{'status': 'xx'}", "$.status", Criteria.where(".status").is(Integer.class));
Similarly this
JsonPath.read("{'status': 'xx'}", "$.status", Criteria.where(".status").eq(200));
both cases returns String = "xx"
I would expect it to return either null or empty string as it doesn't match number 200.
Correct #i.bondarenko, I would simply add - for the first check of searching whether status value is an Integer - that he/she should use a Pattern to pass to the filter, like for example
Pattern numberPattern = Pattern.compile("\\d+");
Filter filter = filter(where("status").regex(numberPattern));
Object test = JsonPath.read("{\"status\": \"xx\"}", "$[?].status", filter);
System.out.println("Test : " + test);
That will print Test : []
UPDATED
It is a JSONArray indeed, therefore, you already have the Integers of your whole JSON in that array (if they exist). For example,
Pattern numberPattern = Pattern.compile("\\d+");
Filter filter = filter(where("status").regex(numberPattern));
net.minidev.json.JSONArray test = JsonPath.read("{\"status\": 300}", "$[?].status", filter);
if (!test.isEmpty()) {
for (Object object : test) {
System.out.println("Test : " + object.toString());
}
}
So, there is no need to add try-catch, it is enough to just check the size of your JSONArray result
You should use $[?].status as json path for criteria.
Also where("field").is("value") accept value but not a class.
You could have a look at implementation of Criteria.eq(...)
public Criteria eq(Object o) {
return is(o);
}
Here is the code:
public static void main(String[] args) {
Criteria criteria = Criteria.where("status").gt(10);
Object read = JsonPath.read("{'status': 18}", "$[?].status", criteria);
System.out.println("First: " + read);
read = JsonPath.read("{'status': 2}", "$[?].status", criteria);
System.out.println("Second: " + read);
criteria = Criteria.where("status").is("value");
read = JsonPath.read("{'status': 'value'}", "$[?].status", criteria);
System.out.println("Third: " + read);
criteria = Criteria.where("status").is("value");
read = JsonPath.read("{'status': 'NON'}", "$[?].status", criteria);
System.out.println("Third: " + read);
}
Output:
First: [18]
Second: []
Third: ["value"]
Third: []

Can’t convert String into json, and it seems that it will be superfluous for the entire string.
Was thinking maybe json might have helped me out here, but it doesn't seem to give me what I want or I don't know how it will be work.
How I can check the string?
I need to check:
METHOD: GET and URL: http://google.com/
also to check the BODY contains the fields userId, replId and view (no values, only keys)
I was trying to find a way to check that:
if (msg.contains("METHOD: GET") && msg.contains("URL: http://google.com/") && msg.contains("BODY: etc...")) {
System.out.println("ok");
}
It doesn't work. Some values from BODY that are dynamic and that's why for BODY the check won't pass if it’s so hardcoded String. And I guess there're any better ways to do that.
I'd like to have something like:
Assert.assertEquals(
msg,
the expected value for METHOD, which contains GET); // same here for URL: http://google.com/
Assert.assertEquals(
msg,
the expected value for BODY that has userId, replId, and view fields); // or make this assertion for each field separately, such as there is an assertion for the userId field, the same assertions for replId and view
And here's the String:
String msg = "METHOD: GET\n" +
"URL: http://google.com/\n" +
"token: 32Asdd1QQdsdsg$ff\n" +
"code: 200\n" +
"stand: test\n" +
"BODY: {\"userId\":\"11022:7\",\"bdaId\":\"110220\",\"replId\":\"fffDss0400rDF\",\"local\":\"not\",\"ttpm\":\"000\",\"view\":true}";
I can't think of any way to check that. Any ideas?
You can use the java.util.List Interface (of type String) and place the string contents into that list. Then you can use the List#contains() method, for example:
String msg = "METHOD: GET\n" +
"URL: http://google.com/\n" +
"token: 32Asdd1QQdsdsg$ff\n" +
"code: 200\n" +
"stand: test\n" +
"BODY: {\"userId\":\"11022:7\",\"bdaId\":\"110220\",\"replId\":\"fffDss0400rDF\",\"local\":\"not\",\"ttpm\":\"000\",\"view\":true}";
// Split contents of msg into list.
java.util.List<String> list = Arrays.asList(msg.split("\n"));
if (list.contains("METHOD: GET")) {
System.out.println("YUP! Got: --> 'METHOD: GET'");
}
else {
System.out.println("NOPE! Don't have: --> 'METHOD: GET'");
}
I've tried to use Assert:
String[] arr1 = msg.split("\n");
Map<String, String> allFieldsMessage = new HashMap<>();
for (String s : arr1) {
String key = s.trim().split(": ")[0];
String value = s.trim().split(": ")[1];
allFieldsMessage.put(key, value);
}
Assert.assertEquals(
allFieldsMessage.get("METHOD"),
"GET"
);
And the same for URL. But my problem is in BODY part. I thought maybe try to parse this particular part of String into json and then only check the necessary keys.
I was trying understand TestReporter in Junit5
#BeforeEach
void beforeEach(TestInfo testInfo) {
}
#ParameterizedTest
#ValueSource(strings = "foo")
void testWithRegularParameterResolver(String argument, TestReporter testReporter) {
testReporter.publishEntry("argument", argument);
}
#AfterEach
void afterEach(TestInfo testInfo) {
// ...
}
what is the use of publishEntry in TestReporter,
Can someone explain me.. Thanks in Advance..
"TestReporter" in conjunction with "TestInfo" gives an instance of the current test, this way you can get info about your actual test. and then publish it, in this example used as kind of logger.
StringBuffer is used for his mutable, fast, and synchonized characteristics, required for a test.
public class TestReporterTest {
StringBuffer sbtags = new StringBuffer();
StringBuffer displayName = new StringBuffer();
StringBuffer className = new StringBuffer();
StringBuffer methodName = new StringBuffer();
#BeforeEach
void init(TestInfo testInfo) {
className.delete( 0, className.length());
className.append( testInfo.getTestClass().get().getName());
displayName.delete( 0, displayName.length());
displayName.append( testInfo.getDisplayName());
methodName.delete( 0, methodName.length());
methodName.append( testInfo.getTestMethod().get().getName());
}
#Test
#DisplayName("testing on reportSingleValue")
void reportSingleValue(TestReporter testReporter) {
testReporter.publishEntry( "className : " + className);
testReporter.publishEntry( "displayName: " + displayName);
testReporter.publishEntry("methodName : " + methodName);
testReporter.publishEntry("algun mensaje de estatus");
}
#Test
void reportKeyValuePair(TestReporter testReporter) {
testReporter.publishEntry( "className : " + className);
testReporter.publishEntry( "displayName: " + displayName);
testReporter.publishEntry("methodName : " + methodName);
testReporter.publishEntry("una Key", "un Value");
}
#Test
void reportMultiKeyValuePairs(TestReporter testReporter) {
Map<String, String> map = new HashMap<>();
map.put("Fast and Furious 8","2018");
map.put("Matrix","1999");
testReporter.publishEntry( "className : " + className);
testReporter.publishEntry( "displayName: " + displayName);
testReporter.publishEntry("methodName : " + methodName);
testReporter.publishEntry(map);
}
}
Running the Test
timestamp = 2019-11-22T12:02:45.898, value = className : TestReporterTest
timestamp = 2019-11-22T12:02:45.904, value = displayName: testing on reportSingleValue

Apart from the previous answers, When we are writing junit test scripts if we want to get some information out of the process we normally do System.out.println which is not recommended in corporate/enterprise world. Specially in code reviews, peer reviews we are advised to remove all the System.out.println from the code base. So in the junit world if we want to push or publish out of the scripts we are advised to use TestReporter publishEntry() method. With the combination of TestInfo we could read several information out of the original junit scripts.
Hope this facts also support your question.
The method name suggests you are publishing a new entry to the report, which is supported by the Java Doc for 5.3.0
https://junit.org/junit5/docs/current/api/org/junit/jupiter/api/TestReporter.html
This would allow you to add additional, useful information to the test report; perhaps you would like to add what the tests initial conditions are to the report or some environmental information.
The code is as shown below. I want it go test all the elements of keyNames.
But, it stops if any test fails and doesn't iterate through all array elements.
My understanding being, in assertAll all assertions are executed, and any failures should be reported together.
Thanks for your time and help.
private void validateData(SearchHit searchResult, String [] line){
for(Integer key : keyNames){
String expectedValue = getExpectedValue(line, key);
String elementName = mappingProperties.getProperty(key.toString());
if (elementName != null && elementName.contains(HEADER)){
assertAll(
() -> assumingThat((expectedValue != null && expectedValue.length() > 0),
() -> {
String actualValue = testHelper.getHeaderData(searchResult, elementName);
if(expectedValue != null) {
assertEquals(expectedValue, actualValue, " ###Element Name -> " + elementName +" : Excepted Value ### " + expectedValue + " ### Actual Value ###" + actualValue);
}
}
)
);
}
}
}
The javadoc of Assertions.assertAll() states :
Asserts that all supplied executables do not throw exceptions.
And actually you provide a single Executable in assertAll() at each iteration.
So a failure in any iteration of the loop terminates the test execution.
In fact you invoke multiple times assertAll() by requesting at most a single assertion at each time :
if(expectedValue != null) {
assertEquals(expectedValue, actualValue, " ###Element Name -> " + elementName +" : Excepted Value ### " + expectedValue + " ### Actual Value ###" + actualValue);
}
What you want is doing the reverse : invoking assertAll() by passing multiple Executable instances performing the required assertions.
So you could collect them in a List with a classic loop and pass it in this way :
assertAll(list.stream()) or creating a Stream<Executable> without any collect and pass it directly such as assertAll(stream).
Here is a version with Stream (not tested at all) but you should get the idea :
Stream<Executable> executables =
keyNames.stream()
.map(key->
// create an executable for each value of the streamed list
()-> {
String expectedValue = getExpectedValue(line, key);
String elementName = mappingProperties.getProperty(key.toString());
if (elementName != null && elementName.contains(HEADER)){
assumingThat((expectedValue != null && expectedValue.length() > 0),
() -> {
String actualValue = testHelper.getHeaderData(searchResult, elementName);
if(expectedValue != null) {
assertEquals(expectedValue, actualValue, " ###Element Name -> " + elementName +" : Excepted Value ### " + expectedValue + " ### Actual Value ###" + actualValue);
}
}
);
}
}
);
Assertions.assertAll(executables);
assertAll() groups all assertions and errors that were passed to that invocation of assertAll(). It won't group assertions across all invocations that occur during the test method.
In the code you posted, you pass a single assertion lambda into assertAll(). It won't group errors across the multiple keys, as each key has a separate invocation of assertAll().
To ensure you separately test all values in a collection, take a look at parameterized tests.
As indicated by #user31601, parameterized tests (see documentation) automatically test all cases independently.
This leads to the following (somewhat simpler) code):
#ParameterizedTest
#MethodSource("getKeys")
void testKey(String key) {
String elementName = mappingProperties.getProperty(key.toString());
assumeTrue(elementName != null);
assumeTrue(elementName.contains(HEADER));
String expectedValue = getExpectedValue(line, key);
assumeTrue(expectedValue != null);
assumeTrue(expectedValue.length() > 0);
String actualValue = testHelper.getHeaderData(searchResult, elementName);
String doc = String.format("name: %s, expected %s, actual %s", elementName, expectedValue, actualValue);
assertEquals(expectedValue, actualValue, doc);
}
private static Stream<String> getKeys() {
return keyNames.stream()
}
I am working on a project, using cassandra 1.2, hadoop 1.2
I have created my normal cassandra mapper and reducer, but I want to create my own Input format class, which will read the records from cassandra, and I'll get the desired column's value, by splitting that value using splitting and indexing ,
so, I planned to create custom Format class. but I'm confused and not able to know, how would I make it? What classes are to be extend and implement, and how I will able to fetch the row key, column name, columns value etc.
I have my Mapperclass as follow:
public class MyMapper extends
Mapper<ByteBuffer, SortedMap<ByteBuffer, IColumn>, Text, Text> {
private Text word = new Text();
MyJDBC db = new MyJDBC();
public void map(ByteBuffer key, SortedMap<ByteBuffer, IColumn> columns,
Context context) throws IOException, InterruptedException {
long std_id = Long.parseLong(ByteBufferUtil.string(key));
long newSavePoint = 0;
if (columns.values().isEmpty()) {
System.out.println("EMPTY ITERATOR");
sb.append("column_N/A" + ":" + "N/A" + " , ");
} else {
for (IColumn cell : columns.values()) {
name = ByteBufferUtil.string(cell.name());
String value = null;
if (name.contains("int")) {
value = String.valueOf(ByteBufferUtil.toInt(cell.value()));
} else {
value = ByteBufferUtil.string(cell.value());
}
String[] data = value.toString().split(",");
// if (data[0].equalsIgnoreCase("login")) {
Long[] dif = getDateDiffe(d1, d2);
// logics i want to perform inside my custominput class , rather here, i just want a simple mapper class
if (condition1 && condition2) {
myhits++;
sb.append(":\t " + data[0] + " " + data[2] + " "+ data[1] /* + " " + data[3] */+ "\n");
newSavePoint = d2;
}
}
sb.append("~" + like + "~" + newSavePoint + "~");
word.set(sb.toString().replace("\t", ""));
}
db.setInterval(Long.parseLong(ByteBufferUtil.string(key)), newSavePoint);
db.setHits(Long.parseLong(ByteBufferUtil.string(key)), like + "");
context.write(new Text(ByteBufferUtil.string(key)), word);
}
I want to decrease my Mapper Class logics, and want to perform same calculations on my custom input class.
Please help, i wish for the positive r4esponse from stackies...
You can do the intended task by moving the Mapper logic to your custom input class (as you have indicated already)
I found this nice post which explains a similar problem statement as you have. I think it might solve your problem.
I need to add some or clauses to query. I need to do it in a loop.
StringTokenizer st = new StringTokenizer(symptoms, ",");
while(st.hasMoreTokens()){
qb.whereOr(Properties.Symptom.like("%" + st.nextToken() + "%"));
}
How I can add those or conditions properly, because this above is not working as expected. I want to add or for every symptom.
If you look at the documentation, you'll see that whereOr() takes an unbounded number of conditions. What you want to do is add them all at once in an array:
StringTokenizer st = new StringTokenizer(symptoms, ",");
ArrayList<WhereCondition> whereConditions = new ArrayList<WhereCondition>();
while(st.hasMoreTokens()){
whereConditions.add(Properties.Symptom.like("%" + st.nextToken() + "%"));
}
// Give the ArrayList an already allocated array to place its contents in.
WhereCondition[] conditionsArray = new WhereCondition[whereConditions.size()];
conditionsArray = whereConditions.toArray(conditionsArray);
qb.whereOr(conditionsArray);
It looks like the method call in the documentation takes two non-array WhereConditions and then an ellipsized argument, which accepts an array or an additional comma-separated list of objects. So you might have to do something like this to get it to work properly:
qb.whereOr(conditionsArray[0], conditionsArray[1], Arrays.copyOfRange(conditionsArray, 2, conditionsArray.length));
ADDENDUM: It looks like you're using APIs that don't match the documentation, possibly an older version of greenDAO. I wrote this solution based off the current documentation. I can't guarantee that it will work for you. I recommend updating if possible.
Try this:
StringTokenizer st = new StringTokenizer(symptoms, ",");
WhereCondition where = null;
while(st.hasMoreTokens()){
if (where != null) {
where = qb.or(where, Properties.Symptom.like("%" + st.nextToken() + "%"));
} else {
where = Properties.Symptom.like("%" + st.nextToken() + "%");
}
}
qb.where(where).list();
I had the same problem so I added my own method in an Util class to perform the same behavior when I have one or several WhereCondition in an array.
Here is my gateway method :
public static QueryBuilder whereOr(QueryBuilder queryBuilder, WhereCondition[] whereConditions){
if(whereConditions == null) return queryBuilder.where(null);
else if(whereConditions.length == 1) return queryBuilder.where(whereConditions[0]);
else return queryBuilder.whereOr(whereConditions[0], whereConditions[1], Arrays.copyOfRange(whereConditions, 2, whereConditions.length));
}
Use : Util.whereOr(queryBuilder, whereConditionsArray);
Default : Can't use the Builder Pattern from the QueryBuilder with this approach
(More later) Here, I share you some code which could spare you time when developping DAO methods.
public class QueryBuilderUtil {
public static final String EQ = "=?";
public static final String NOTEQ = "<>?";
public static final String LIKE = " LIKE ?";
public static final String GE = ">=?";
public static final String LE = "<=?";
public static final String GT = ">?";
public static final String LT = "<?";
public static QueryBuilder whereOrOnSamePropertyWithDifferentValues(QueryBuilder queryBuilder, Property property, String operation, String values, String separator) {
return whereOrOnSamePropertyWithDifferentValues(queryBuilder, property, operation, values.split(separator));
}
public static QueryBuilder whereOrOnSamePropertyWithDifferentValues(QueryBuilder queryBuilder, Property property, String operation, String[] values) {
WhereCondition[] whereConditions = new WhereCondition[values.length];
int i = 0;
for (String value : values) {
whereConditions[i++] = new WhereCondition.PropertyCondition(property, operation, value);
}
return whereOr(queryBuilder, whereConditions);
}
public static QueryBuilder whereOr(QueryBuilder queryBuilder, WhereCondition[] whereConditions) {
if (whereConditions == null) return queryBuilder.where(null);
else if (whereConditions.length == 1) return queryBuilder.where(whereConditions[0]);
else return queryBuilder.whereOr(whereConditions[0], whereConditions[1], Arrays.copyOfRange(whereConditions, 2, whereConditions.length));
}
}
With this class, you can perform a whereOr with the same property on multiples "values string" in one line. It was necessary to clean my code :). However you can only do simple operations like variables declared in the class.
Example :
public List<Block> loadAllByModId(String mods_id) {
synchronized (this) {
QueryBuilder<Block> queryBuilder = queryBuilder();
QueryBuilderUtil.whereOrOnSamePropertyWithDifferentValues(queryBuilder, Properties.ModId, QueryBuilderUtil.EQ, mods_id, ";");
query_list = queryBuilder.build();
}
Query<Block> query = query_list.forCurrentThread();
return query.list();
}
Hope it helps
